In her 'Folded Map Project', US artist Tonika Johnson tackles Chicago's urban segregation

Chicago's segregated residents are unexpectedly becoming friends in a project that an artist hopes will smash barriers and stereotypes.

When Tonika Johnson started photographing houses with corresponding addresses in the city's North and South sides in her Folded Map Project, she decided to bring the residents together. The North Side is a largely affluent, white area, while the South Side is traditionally African-American, and has suffered with poverty and gun violence.
